Australia's cricketers are threatening to boycott next month's Indian Premier League (IPL) if their security demands for the Twenty20 tournament aren't met.

Player groups from around the world are hastily putting together a list of concerns for the Federation for International Cricketers' Association (FICA) to hand to IPL organisers.

The security situation has worsened in India this month with a direct threat from an Al-Qaeda affiliated terrorist group to the IPL, the hockey World Cup and this year's Commonwealth Games.

Australian Cricketers' Association boss Paul Marsh said his players' participation in the tournament was no certainty following a crisis meeting with players and managers in Sydney on Tuesday.

"I think it is very difficult to say at the moment," he said.

"There are some issues that have been raised, if the IPL can satisfy those issues then potentially the players will be in a position to go."

Marsh said the players wouldn't be blindly lured by the riches of the IPL, which begins on March 12.

"All the money in the world is not going to help you if you are not around to spend it," he said.

Marsh said widely-respected consultant Reg Dickason's security report had exposed serious shortcomings in the IPL's plans but he refused to go into detail about the problem areas.

IPL bosses have refused in the past to acknowledge FICA but Marsh was confident backroom dealings could assist in them coming to an agreement.

The Australian players would be open to the tournament being shifted to South Africa for the second consecutive time.

"From our players' perspective, that would ease a lot of fears," Marsh said.

The Australians are an important part of the IPL's attraction with the likes of Shane Warne, Andrew Symonds, Adam Gilchrist and Matthew Hayden not only major drawcards but also available for the tournament's entire duration unlike most international stars.

"We have got about 25 players involved so it would be a lesser tournament (without them)," said Marsh.

"But as I said at the moment our players want to go to the IPL, we have some issues we are trying to work through."

IPL chief Lalit Modi was trying to take the heat out of the argument on Tuesday night.

"I spoke to a couple of the (Australian) boys yesterday about it. I think they will all take part," he told AAP.

"The tournament will go on. They are very comfortable with it. Not all players have said they don't want to come, some have had concerns and we have taken care of their concerns.

"There's nothing to be concerned about."

Modi pointed to the Kookaburras' presence in India for the World Cup hockey tournament as proof the country was safe for sports stars.

But as Marsh pointed out, the hockey tournament and the IPL are very different beasts.

The hockey players are all at one hotel and play in one city while the eight IPL teams play at 12 different venues with teams completing around 20 flights per tournament according to Marsh.

Australian hockey star Jamie Dwyer told AAP the Kookaburras were "very comfortable" with security arrangements at their hotel and the New Delhi's Major Dhyan Chand National Stadium.

I Just cant understand, we have only few months left for the World Cup. If playing in India is not safe now, then how come aussies, poms will feel safe during the WC ? this IPL would be a perfect dress rehearsal for the big event.
